` 'citizen of ttennicedrstas; 'residing apnea-s ville,fin the county of Tyler and 'State of West y 5 Virginia, haveinvented anew and usefulCar- Coupling, 'of which thefollowing isa specification. A l A l Theinvention relates rto improvements in car-couplings. l The objectof the present invention isto improve the construction of pin-and-linkcar- 'couplings' and to provide a simple, inexpensive, and efficient device capable of coupling automatically when two cars come together and adapted to be readily uncoupled.

A furtherobject of the invention is to pro-L vide a car-coupling of this character in which the parts may be readily arranged for coup-f ling without necessitating a person going 1 zo between cars and'V in which the link will be supported in position. for guidingit'into the month of the draw-head.

`Another object' of the invention is to pro'- vide'me'ans forvsupp'orting apair of links adjacent to the mouth of a draw-headand to yenable-one of them tombe readily swung into ,operative position from either side of acar,

- -so that the parts maybequickly set `for au-Y tomatic couplingwithout dangerjto theop-n 3o erator.

The invention. consists in-the construction '-andnovel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointedv n vIn Vthe drawings, Figure 1 1s a perspective lView of a car-coupling constructed in accord- 35 vout in the claims hereto appended.

a coiled spring 4 disposed on lit and interposedbetween the back of the open frame and the'back of the drawhead,as clearlyl illustrated,inFigs.,.2y and 3 of the accompanying drawings. Within the fraineis arranged'a vertically-movable bar 5, provided with front and rear, longitudinahrihs or.

flanges and having av recessv 6 fat its back to be engagedv by; the spring-actuated frame,

` whereby the bar is supported in "an elevated position, and the front of the frame is adapt- 't .vicer'Zslidingwithin'it and consisting of an Y open `'fra mev oljsub'stantiall y rectangular form thev frainebengjslightly `tapered`,"a's shown, i and having front and rear`V transverse por?. tions. Y`vTh'efranrie ofthe'spring-actuated pin#l .support` is lprovided with a rearwardly-ex- .tending stem, guided-in a suitablefperfora- Y tion lor opening of the draw-head and having ed to be engaged bya link entering the vdrawv head, 'whereby the backfof'thefrarne will be be carried out of. the recess Vto cause'the bar to fall and carryacouplingfpin 7'in engagement with thelink S.v Thedrawhead is provided 'withr a coupling-pin perforation 9,' and `4it has axrear perforation or opening l0, conforming to ,the configuration of the flanged y orribhed bare. n The bar' 5 supports a horizontal bar il, extending forward ,and `rearward from the upper end of the'said bar 5 and forming arms, the forwardly-extending arm being provided witha perforationV for the reception ofthe coupling-pin; zontal bar 11 is provided with an eye and is designed to be' connectedwith any suitable uncouplin g mechanism; but as the verticali)7` `movable 'loarv extends entirely through thedrawhead uncoupling mechanism may be arv .ranged to liftthe bar 5 from below. lWhen The horithe baris elevated, the pin is not only car-` also set for automatic coupling.V

"fied out of engagement with alink, but it is Y In order to facilitate-the'couplingand to` enable the drawhead to be quickly supplied site sides of the draw-head, asclearly illustrated inFigs. landv 2 of the accompanying 9s with a link without necessitating the operaf Vtorgoingbetween two cars, a pair Vof links S 1areprovided, and they are supported at oppoloo drawings, byl curved bars 12 provided with l ,slotSlS forthe reception ofthe links and car- '1 I rying vertical v'pins or fastening devices 14, which pass through the links. The mouth of the draw-head is enlarged at 15 to receive either of the curved bars, which are adapted to lie Wholly in the said draw-head` as clearly shown in Figs. 2 and 3, and the inner ends of the curved bars 12 are reduced to form tongues 16, which are secu red in slots or bit' urcations 17 of the sides of the draw-head by vertical pivots 18. The links which extend through the slots of the curved bars project in advance and in rear of the same, and the rear or inner portion engages the springac tuated frame when the curved bar is swung within the draw-head. This causes, the coupling-pin to fall and engage the.link,and when the pin is in engagement with the link the entire, strain. is borne bythe coupling-.pins and the said link,a nd the pivots of the Curved bars and the pinsl 1% of the saine are not sub.,- jected to any'strain and do not require to be of extraordinary strength.

The draw-headisprovided at oppositesides with hooks 19, arranged toengage the links, as illustrated in Fig. 2 of the drawings, whereby the link which is not in actual use is held against movement and is prevented from being swung around by the vibration of the draw-head. The curved arms which support the links in a, horizontal position for guiding thelninto the mouth of a draw-head also support the links in position to be engaged by the hooks; but any other suitable fastening devices may be employed for securing the links to the sides of the draw-head.

.The invention has the following advantages: The car-coup.ling, which issimple and comparatively inexpensive in construction, possesses great strength andAV durability, and it is positive, reliable, and automatic in its operation and the links, which are arrangedy at opposite sides of the draw-head, are adapted to be swung into the same, so that the parts may be set for coupling from either side of a car/withouty going between two cars. When one of the linksis in use,the other is anchored or fastened to the adjacentside of the drawhead and is. prevented from being thrown about by the vibration of the car-coupling. The draw-head, which is the same at the top and bottom, is adaptcifl tobe, reversed, and-it may be applied to ay car in any suitable manner; also, any form of operating mechanism may be connected with the vertically-movable device which carries they coupling-pin, and such operating mechanism may beconnected with either the top or bottom of the vertically-movable device.

Changes in the form,y proportion, size, and the minor details of construction Within the scope of the appended claims may be resorted tionsand slidingly mounted in the drawhad,

a spring engaging the frame and adapted to move the same outward, a coupling-pin located in advance of the frame, and a vertically-movable pin-support comprising a bar passing through the draw-head and arranged to be engagedby the rear transverse portion of the frame, saidv barbeing provided at its top with a forwardly-extending arxn receiving the coupling-pin,` substantially as described.

2. In a car-coupling, the combination of a d raw-head, a coupling-pin, a link, and a` horizontally-swingingsupport hinged to the drawhead at one side thereof andreceiving the link and supporting the samein thesaine/horiZon tal plane as, the monthy of thevdrawhead,^said link-support being adapted to carry the link into and out of the draw-head, substantially as described.

3. In a car-coupling, the combination of a draw-head, a link, and horizontallyswinging barhinged to the draw-head at one'sidel there'- of, and provided with a slot receiving the link, said bar supporting the linkin the sarne horizontal plane as the mouth of the draw-head and adapted t-o swing the link into and out of the same, substantially as described.

. 4. In a car-.couplingthe combination of a draw-head, a pair of Vhorizontally-swinging link-supports hinged to the draw-head at opposite sides thereof, and links mounted on the supports and arranged in the same horizontal plane, as the mouth of the draw-head, either of the links being adapted to be swung into andout of the draw-head, substantially as described. l

5. In a car-coupling, the combination of a draw-head, a pair of horizontally-swinging link-supports hinged to the draw-head atopposite sides thereof, links mounted on the supports and arranged in the same horizontal plane as they 'mouth of theA draw-head, either f the links bei-ng adapted to be swung into and out of the same, and fastening devices mounted on the draw-head atv opposite sides thereof and engaging the links, substantially as and for the purpose described.

In testimony'that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
